"Rough" surface on edge of flat print

Hi!

I'm currently trying to print a case for some hex drivers I have, but am running into issues:

The "rough" edge pictures here is supposed to be flat. It happens only on this side, the other side prints how it is supposed to.

I am currently printing with PLA with the bed set to 65 and 210 first layer / 195 all others, I have the fan set to 'off' for the first 3 layers and then on for all others.

Here are my Slic3r Prusa Edition settings (for some reason it wouldn't let me upload more images):

I've also had some bad bed adhesion issues, currently the print that I am referencing for this I had to use hairspray on the bed to get it to stick, could these issues be related? I had originally thought this was related to poor bed adhesion, but it sticks with hairspray and the issue has persisted.

From another failed print:

What I've tried:

  • Turning the fan off for the entirety of the print

  • Changing bed temperature

  • Changing extruder temperature

  • Changing the flow multiplier (from 1 to 0.93)
  • Let me know if you need any more information.

    Any help is appreciated!

    Thanks

    I would print something from the SD card to determine if it is your printer hardware, or your slicer software.

    Hi Jeffrey

    It seems the over-extrusion occurs only some mm over the bed... 🙄

    It's exactly my case also... Did you fixed this issue ?

    Your Slicr parameters are more or less the same.

    Hi Vincent,
    your prints really look horrible.
    what are your slic3r settings ? especially fill density and infill overlap ? number of outer perimeters (vertical shells) ?
    did you calibrate your extruder (search for the 10cm trick) ?
    are all the pulleys and bells "tight" (ohne Spiel) ?
    does your filament run smooth from your spool ?

    furthermore: how does the print of *.gcodes look like that came with the printer (for example the prusa whistle) ?

    dem inscheniör is' nix zu schwör...

    Hi

    Fill density is very low (10%) and vertical shels is set to 3.
    What is the infill overlap ?

    Yes, extruder has been calibrated (85 mm consumption for 100mm asking) but I have the same result with extrusion multiplier = 1 (under extrusion)

    I will check the pulleys ...

    but my belts are very tigh. I didn't found the way to find out the right strain !

    Thank for your help and ... Happy new year !

    .... By the way, infill overlap is 25% !
